(incremental type)
POINT
This linear encoder is of four-wire type. When using this linear encoder, change
the parameter to select the four-wire type. For changing parameters, refer to
each servo amplifier instruction manual.
When using a linear encoder of four-wire type with fully closed loop control, use
an MR-J4-(DU)_A_-RJ/MR-J4-(DU)_B_-RJ.
When using a linear encoder of four-wire type with scale measurement function,
use an MR-J4-(DU)_B_-RJ.
